BOSSMS-3 Multi-Effects Switcher
1/4
Independent shopping perspective
The Korena take
BOSS’s MS-3 combines a multi-effects processor with a three-loop pedal switcher, making it the control center for a compact hybrid guitar or bass rig. Put three external effects in its loops, place the onboard effects around them as needed, and run up to six internal effects at once. Its 112 effect types cover FX, modulation, delay, and reverb categories, while 200 patch locations keep song-ready routing and control assignments close at hand. MIDI, amp-channel control, stereo or patch-selectable mono outputs, and USB editing broaden its role beyond a basic switcher.
Strong match
Who this is for
- Combining three favorite external pedals with onboard effects in a compact pedalboard system.
- Recalling stored routing, effects, and control setups quickly across songs or different performance configurations.
- Controlling compatible MIDI devices and amp channels from one foot-operated switching hub.
Consider the trade-offs
When to look elsewhere
- A rig requiring more than three external effects devices in the MS-3 audio loops.
- An effects system that needs more than six internal effects running simultaneously.
